Halogen headlamp

Date:Oct 10, 2019

Halogen headlamp is a new generation of incandescent lamp, filled with bromo-iodine halogen elements or halogen tungsten lamp. In order to improve the luminous efficiency of incandescent lamps, the temperature of tungsten filament must be raised, but the corresponding sublimation of tungsten will cause it to coagulate on the glass shell and make it black. If halogenated elements or halides are filled into the incandescent lamp, the phenomenon of black glass shell can be eliminated by using the principle of halogen tungsten cycle.
